You guys are correct. I continued to try and find a doc that supported my
understanding only to find that I was wrong.
We setup a lab environment with the following setup.
E1 = 192.168.1.1 /24
S0/0 = 10.1.1.1 /8
Router Rip
Network 10.0.0.0
Debug ip rip
The debug trace shows RIP updates only being sent out the S0/0 port.
Sorry for misleading anyone, but as it was stated earlier, you learn
something new every day!!!!!

That's what I thought. I'll try doing a test at home on my
setup and see
what it yields.
